Controls for phones or tablets

Hello, I have a doubt that is not resolved, I have seen that for these devices the controls are with the two joystick, but my question is and if I want to move with touches on the screen ???.
The game is type of age of empire.

Thanks in advance.

in the learn tab of the epic launcher, i think the following learning samples will help you

turn based strategy sample

Thanks for answering but it is not what I am looking for, what I want is to create an age of empires for tablet, and what I need to know is how to move the troops with the touch of the screen but without the joistik.
